FUR CLIPPING AND UNHAIRING MACHINE.

SPECIFICATION forming pm of Letters Patent No. 309,878, dated December30, 1824..

Application filed August 14, 1884.

the fur clipping and unhairing machine for which United States LettersPatent No. 275, 07 7 were issued to me on the 3d day of April, 1883,

consists in the combination, with a strip over which the fur to beclipped is passed, knives for cutting off hairs of the fur, and anairforcing apparatus, of combs or strips for holding down some of thehairs that have been laid down by the current of air, which combs are soarranged that they will be first moved toward each other and then moveddownward by a suitable mechanism.

The invention consists in various parts and details and combinations ofthe same, as will be fully described and set forth' hereinafter.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a longitudinal sectional elevation of my improved furclipping and unhairing machine, showing it provided with my improvementsfor operating the comb. Fig. 2 is a side view of the mechanism foroperating the combs, showing the combs drawn toward each other. Fig. 3is a like view showing the combs drawn toward each other and lowered.Fig. 4 is a sectional plan view on theline 00 :17, Fig. 2. Fig. 5 is across-sectional viewon the line ;I y, Fig. 4.

The combs A aresecured at each end to the upper ends of upright platesB, provided in their upper and lower ends with transverse slots 0,through which pins D, carrying rollers, pass into a plate, E, held toslide vertically in a recess, F, in the side frame, G, of the machine.The plates B are adapted to (No model.)

slide toward and from each other on the plate E; but they cannot slidevertically on the said plate E. The plate E can slide vertically in therecess in the frame Gr, but cannot slide laterally. A bent lever, H,pivoted in the machine-frame, has its rear end resting on a cam, J,mounted on a shaft, K, which rear end of the lever H is pressed on thecam J by a spring, J, secured to the leverH and to the machine-frame.

To the lower front end of the leverH an upwardly-projectingconnecting-bar, L, is pivoted,'to which links M are pivoted, which havetheir opposite ends pivoted to the sides of the two plates B. TheplateEis drawn up ward by a spiral spring, N. The fur to be clipped orunha'ired is stretched over a plate or board, a, which is locatedbetween and be low the combs, and the upper edge of the said plate orstrip is so arranged in relation to the combs that when the combs aredrawn downward and toward each other so far as possible the toothededges of the combs will be almost in contact with the upper edges of thesaid plate a. The current of air is produced in a blower, T, providedwith a valve, U, in its spout T", below which spout a sliding nozzle, V,is held, which extends the err tire length of the plate a, over whichthe fur is stretched. The hairs are clipped off by a sliding knife, R,and by a rotary spiralknife, A. Suitable devices are provided for movingthe knives and stretching and feeding the fur.

The operation is as follows: If the cam J raises the rear end of thelever H, the front end will be drawn downward and the connect ing-rod Lwill be drawn downward. The re sistance offered by the spring N preventsthe plate E from being drawn downward, and causes the links M to drawthe plates B and the combs A, secured to the same, toward each otheruntil the outer ends of the slots 0 strike against the pins D. Theplates B cannot be moved toward each other any farther, as shown in Fig.2, and the forceexerted by the lever H now overcomes the tension of thespring N and draws the plate E, and with it the plates B and the combsA, downward, as shown in Fig. 3. The edges of the combs A will then holddown the hairs that have been laid down by the current of air issuingthrough the nozzle NV. As the shaft K completes its revolution thespring J, or another suitable device provided, presses down the rear endof the lever H, whereby the front end will be moved upward and theconnecting-rod Lwill be moved upward, and thereby the plates B will bemoved from each other until the inner ends strike the pins D, wherebythe combs are separated, and then the plate E and the plates B and combsA, held on the same,will be raised, and so on. In place ofcombs, metalstrips may be used.

I am aware that combs have heretofore been used on fur-clippingmachines, the same being shown in the patent of Gimiotti, granted April12, 1881, No. 240,007, and my patent granted April 3, 1883, No. 275,077,and I there fore do not claim such invention.

Having thus described my in vention,I claim as new and desire to secureby Letters Patent 1. In a machine for clipping and unhairing fur, theeombination,with a strip over the edge of which the skin is to bepassed, of an airforcing apparatus, knives for cutting off hairs of thefur, and of combs or plates for holding down some of the hairs, whichcombs are arranged to first move toward each other and then downward,essentially as herein shown and described.

2. In a machine for clipping and unhairing fur, the eombination,with astrip over the edge of which the skin is to be passed, of an airforcingapparatus, knives for cutting off hairs of the fur, and of combs orplates attached to upright plates, adapted .to be moved toward eachother and then drawn downward, substantially as herein shown anddescribed.

3. In a machine for clipping and unhairing fur, the eombination,with astrip over the edge of which the skin is to be passed, of an airforcingapparatus, knives for cutting off hairs of the fur, combs or plates,upright strips or plates to which the said combs or plates are fastenedat the ends, and of means for drawing the said plates to which the combsare fastened toward each other and then downward, substantially asherein shown and described.

4. In a machine for clipping and unhairing fur, the combination, with astrip over the edge of which the skin is to be passed, of an airforcingapparatus, knives for cutting ofl' hairs of the fur, and of combs orplates having their ends securedto upright plates provided withtransverse sl ots,through which pins are passed into avertically-movable plate, and of links connecting the said slottedplates with a connecting-bar having an up-ancbdown movement,substantially as herein shown and described.

5. In a machine for clipping and unhairing fur, the eombination,withastrip over the edge of which the skin is to be passed, of an airforcing apparatus, knives for cutting off hairs of the fur, combs orplates having their ends secured to upright plates provided withtransverse slots, through which pins pass into a vertically-movableplate, means for drawing the vertically-movable plate upward, and oflinks connecting the upright plates with a connectingrod having anup-and-down movement, substantially as herein shown and described.

6. In a machine for clipping and unhairing fur, the eombination,with astrip over the edge of which the skin is to be passed, of an airforcingapparatus, knives for cutting ofi hairs of the fur, combs or plateshaving their ends secured to upright plates B, provided with transverseslots 0, a vertically-movable plate, E, pins D, passed through the slots0 into the plate E, the spring N, for drawing the plate E upward, thelever H, connecting-rod L, pivoted to the lower end of the lever H, andthe links M, connecting the plates B with the connecting'rod L,substantially as herein shown an d described.
